ADJUSTMENT OF THE OVEN BUR-
NER MINIMUM
This needs to be done only for the oven
burner (the grill is a xed capacity) by ac-
ting on the thermostat.
Considering that in the minimum position
the ame must have a length of about 4
mm and must remain lit even with a bru-
sque passage from the maximum position
to that of minimum.
The ame adjustment is done in the fol-
lowing way:
turn on the burner by setting the ther-
mostat knob on position 285 (maxi-
mum);
remove the knob and unscrew the by-
pass screw G(g. 8.13) about three
times by passing a small at screwdri-
ver 3 mm blade, 100 mm length)
through the panel opening;
re-mount the knob and let the oven
heat up for about 10 minutes, then
bring the knob to position 150 (mini-
mum) to operate the thermostat by-
pass;
after having removed the knob again
and being very careful not to turn the
tap rod, slowly screw the by-pass
screws G(g. 8.13) until you obtain
a ame of 3-4 mm in height.
N.B. For G30/G31 (LPG) the by-pass
screw must be xed thoroughly.
